Because I don't know anything about modern 3dmark... I'm guessing those are great scores. The site says a 2080Ti gets 31,000+. The only way to go higher would be a CLR chip.
The temps are fantastic, are you happy with the card though?

I would say these would probably come packed with the highest binned silicon, usually reserved for Epyc. Orders for Epyc must be slowing down now as AMD is set to release the new parts shortly.

In this day and age... how hard is it really to expand the BIOS chips sizes though?
But for the boards that have already been made I can see it being a huge headache for motherboard manufacturers. As they will have to remove CPU compatibility from boards that might render them useless to the unsuspecting person using a board chip combo that could be broken by an update. Not a lot of planning was put into this... and I blame AMD.
